Power BI consulting involves six key phases: discovery, data assessment, solution design, development, testing, and deployment. The discovery phase identifies business goals and key metrics. Data assessment evaluates data sources, quality, and accessibility. In solution design, consultants define architecture, reports, and KPIs. Development focuses on building data models, dashboards, and analytics. Testing ensures functionality, accuracy, and performance. Deployment involves publishing dashboards, training users, and setting up governance policies. By following these phases, Power BI consulting deliver tailored solutions that align with business needs, ensuring a seamless transition to data-driven decision-making.
